gears meshing therewith and operated by a hand wheel or a crank.

When a large number of magazines are super- H posedly arranged, it has been found that the 15 articular connections of the rack bars with the magazine frame heretofore employed, occupy considerable space vertically and it is difficult to allow for the required shifting range of movement.

06 The invention aims at providing a construction for the operation of the rack bars on the magazine frame which, although it complies with all requirements in respect of adjustability, requires comparatively little space, so that the disadvantages existing in previous constructions are eliminated.

With this object in view the invention consists in a typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising said magazines comprising a member which is associated with said supporting frame by adjustable means allowing accurate adjustment of said frame in relation to said raising means.

In the accompanying drawing, one constructional form of the invention, shown by way of example only, is illustrated, and in the said drawing:-

Figure l is a side elevation, partly in section, of 40 the pertinent parts of the machine, and

Figure 2 is a section through Figure 1, taken on the line 2-2, looking in the direction of the arrow.

In the constructional form of the machine illustrated in the drawing, a is the magazine supporting frame upon which are located, in the present construction, four magazines b. For raising and lowering the magazine frame in order to adjust the magazines, rack bars are articular- 50 ly connected to the suporting frame, and engage toothed gears cl, the shafts e of which for instance, through a bevel pinion gearing mechanism, are in engagement with a shaft g driven by a crank handle so that by turning the 55 crank handle ,1 the magazine column may be raised or lowered. Such an arrangement is of known form.

The invention is concerned with the attachment of the rack bars to the supporting frame. For this purpose, levers h are provided rotatably "5 mounted upon pivots h in bearers 2, which in turn, by means of screws or the like, are screwed in the supporting bar It or the like attached in a transverse direction to the supporting frame.

At their free end, the levers h carry each a bolt m with which the rack bars 0 are engaged, so that the latter are thereby articulated with the levers h. Further, at the side of each lever h is arranged a downwardly curved projection n which is provided with a slot through which f5 passes a bolt 0. One end of this bolt is screwed into the magazine supporting frame or in a transverse ledge 11, provided thereon, and is secured by a lock nut. The downwardly projecting free end of the bolt is embraced by the slot of the lug n and above and beneath the lug are arranged nuts (1, q by means of which an upward adjustment of the lever h is made possible.

With the arrangement described, the necessary accurate adjustment of the supporting frame, or of the magazines relatively to the rack bars can therefore be effected. The rack bars themselves nevertheless rest closely against the lower edge of the supporting frame, so that the space beneath the supporting frame is fully utilized for the purpose of shifting the magazines.

It should be understood that various modifications of the form of the invention described above may be introduced under different conditions and requirements which have to be fulfilled, without 5 departing in any way from the scope of the invention.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is:-

l. A typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising said magazines comprising a member which is connected indirectly to said supporting frame by adjustable means allowing accurate adjustment of said frame in relation to said raising means.

2. A typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising said magazines comprising a member articulated indirectly to said frame, by adjustable means allowing accurate adjustment of said frame in relation to said raising means.

3. A typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising said magazines comprising a rack operable by a suitable pinion, a link pivoted to said rack and to said supporting frame, and adjustable means extending between said frame and said link at a point on the link remote from its pivot to the frame.

4. A typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising said magazines comprising a rack operable by a suitable pinion, a link pivoted to said rack and to said supporting frame, a bolt extending from said frame, and lock nuts adjustably securing the free end of said link to said bolt.

5. In a typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising and lowering the supporting frame to bring one or another of the magazines into operative position, said means comprising a rack operable by a suitable pinion and extending close up to the magazine supporting frame, and laterally offset connections between said rack and the magazine supporting frame.

6. In a typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising and lowering the supporting frame to bring one or another of the magazines into operative position, said means comprising a rack operable by a suitable pinion and extending close up to the magazine supportin frame, a member depending from the supporting frame and extending alongside the rack, and devices for connecting said member to the rack at a point below the upper end of the rack.

7. In a typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising and lowering the supporting frame to bring one or another of the magazines into operative position, said means comprising a rack operable by a suitable pinion and extending close up to the magazine supporting frame, a member depending from the supporting frame and extending alongside the rack, and devices for connecting said member to the rack at a point below the upper end of the rack, said connecting devices being adjustable to shift the point of connection nearer to or farther from the upper end of the rack.

8. In a typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising and lowering the supporting frame to bring one or another of the magazines into operative position, said means comprising a rack operable by a suitable pinion and extending close up to the magazine supporting frame, a member depending from the supporting frame and extending alongside the rack, and an intermediate element connected to the upper end of the rack and to the depending element at a point below the upper end of the rack.

9. In a typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising and lowering the supporting frame to bring one or another of the magazines into operative position, said means comprising a rack operable by a suitable pinion and extending close up to the magazine supporting frame, a member depending from the supporting frame alongside the rack and terminating at a point below the upper end of the rack, and an intermediate element connected to the upper end of the rack and to the lower end of the depending element.

10. In a typographical composing machine having a plurality of matrix magazines, a supporting frame therefor, and mechanical means for raising and lowering the supporting frame to bring one or another of the magazines into operative position, said means comprising a rack operable by a suitable pinion and extending close up to the magazine supporting frame, a member depending from the supporting frame and extending alongside the rack, and an intermediate element connected to the upper end of the rack and to the depending element at a point below the upper end of the rack, the connection between the intermediate element and the depending member being adjustable to vary the position of the depending member with relation to the rack.
